摘要： To restrain a flutter of a magnetic disk in a high-speed hard disk drive, a ramp 40 is provided so as to be separated with a predetermined space from a side wall 12a of a base 12. Between the side wall 12a and the ramp 40 is formed a bypass channel 42. An air flow is supplied toward a magnetic disk 22 through the bypass channel 42. By using such a configuration, a flutter of the magnetic disk 22 is reduced.

摘要： In attaching a load beam to a carriage, the swage attachment is used between the carriage and a mountplate, while the load beam is attached to the mountplate by welding and other binding means, to create a structure in which the load beam does not come into direct contact with the swage part, so that a structure is obtained in which the load beam is hardly subject to deformation or other direct influences from the swage operation. In addition, by forming the attaching plate side of the load beam to envelope a carriage, or by extending both sides of the load beam from the central portion in the longitudinal direction toward the carriage, a structure improved in the stability of load beam attachment is obtained.

摘要： The present invention provides an improvement to a clamp in a disk drive. Insertion holes are formed in the clamp, and screws are inserted into the insertion holes to fasten the clamp to the spindle. The bottom of the screw head contacts the clamp surface to apply a force to the clamp. However, the clamp does not contact the entire bottom surface of the screw head. Only a portion of the bottom surface of the screw head contacts the clamp to apply a force to the clamp. Since the force caused by tightening the screw is applied only to the area contacting the screw, the force diffuses in a non-contact area in an outer portion of the clamp. Therefore, disk distortion and deformation are decreased.
摘要翻译： 本发明提供对磁盘驱动器中的夹具的改进。 在夹具中形成插入孔，并将螺钉插入到插入孔中，以将夹具紧固到主轴上。 螺钉头的底部接触夹具表面以向夹具施加力。 但是，夹具不接触螺钉头的整个底表面。 只有螺钉头的底部表面的一部分接触夹具才能向夹具施加力。 由于通过拧紧螺钉而产生的力仅施加到与螺钉接触的区域，所以力在夹具外部的非接触区域中扩散。 因此，盘变形和变形减小。

摘要： A disk clamping apparatus for a data storage device fixing at least one disk onto a spindle motor, and having: a clamp combined with the spindle motor and applying pressure onto the disk in a first direction, an outer circumference of the clamp contacting a first part of the disk; and a damper installed between the clamp and the spindle motor to damp impact and vibration delivered to the disk via the clamp. The damper is made of a visco-elastic material and adhered to at least one of a bottom of the clamp or an upper part of the hub. Accordingly, it is possible to damp impacts and vibration delivered to the disk via the clamp, thereby reducing an incidence of the disk bumping against a head, and reducing deterioration of performance of the head.

摘要： A disk clamp has a data position in a recording track that is resistant to positional deviations even after temperature cycling is conducted. The distribution of data positions can be centered in the vicinity of the center position. A disk top clamp and hub are made from materials that are stable in terms of chemical properties over a temperature range in which the disk recording apparatus is used and have such a coefficient of elasticity that a clamping force required to clamp the recording disks while the disk recording apparatus is in use can be obtained from the tightening force to tighten the screws. The material of the top clamp and the hub has a thermal expansion coefficient that is close to that of the recording disk.
